2 Claims.

This invention relates to an improvement in pile fabrics and has for anobject to provide a material of the same general nature as the wellknown'transparent velvet andwhich, while re- 5 taining the advantages oftransparent velvet, ob-

viates allor substantially all of the disadvantages thereof.

Another object consists in providing such a material which is verydurable and wear-resisting, and which retains its appearance in spite ofall normal vicissitudes of wear.

Another object consists in providing such a material which has a noveland attractive appearance.

Another object consists in providing such a material which may be veryeconomically produced.

A further object consists in providing certain improvements in the form,construction and arrangement of the several parts, and in the materialsemployed, whereby the above named and other objects may effectively beattained.

A practical embodiment. of the invention is represented in theaccompanying drawing, in which Fig. 1 represents an enlarged detail planview of the fabric material, and

Fig. 2 represents a section taken in the plane of the line II-II of Fig.1, looking in the direction of the arrows.

A pile fabric commonly known as transparent velvet has become verypopular during the past few years, largely because of its uniqueappearance and charm which arise from its somewhat sheer, transparentand clinging qualities. There has, however, been a general andsubstantial disadvantage in this material because of its delicacy andsusceptibility to injury through ordinary wear and the action of theelements. Transparent velvet is very easily crushed, even by the weightof the wearer, especially when supplemented by the heat of the bodyand/or of the atmosphere; and it is very readily injured by any form ofwetting. A cleaning process is also Very apt to cause it to lose some ofits valuable features..

, My improved fabric has the same sheer, transparent and clingingcharacteristics -as transparent velvet but it firmly resists crushing ormatting as Well as the deleterious effect of moistening. The weight ofthe wearer will not injure it and it will automatically recover from ashower or the like. Furthermore, it may be cleaned without loss of itscharming characteristics. Finally, it is durable and wear-resisting to avery high degreer This fabric material may be woven after the manner ofmost cut pile fabrics, according to which two grounds consisting of warpand weft threads are woven while the pile threads are interwoven andinterlaced back and forth between 5 the two grounds. Thereafter the pilethreads are cut intermediate the grounds to form two fabric materialswith cut pile protruding therefrom.

Referring to the drawing, the ground warp 10 threads are denoted by 1and the weft threads by 2. The pile threads, here woven as warps, aremarked 3. It will be observed that each pile loop goes under two warpthreads and over one intermediate warp thread, thereby forming the 15well known w-weave. The ground threads may be composed of any suitablematerial, such, for instance, as silk, artificial silk, cotton, linen;and

the pile threads may likewise consist of any desired material although,in this case, I prefer to Q0 use articial silk of the acetate variety.

The important characteristic of the invention lconsists in the fact thatthe pile threads, of whatever material they are composed, are twisted toan extent beyond the normal or usual twist of threads used inweavingpile fabrics and, more particularly, velvets. For instance, whileit is customary to give such threads from four to seven twists or turnsper inch, I prefer to use from forty to forty-flve twists or turns perinch. 30 Furthermore, after the fabric has been woven and the pile cut,I do not untwist or brush out the pile tufts but leave them` in theircomparatively tightly twisted condition, which gives a resilient surfacethatis extremely attractive in appearance and free from all the defectshereinabove noted as being characteristic of transparent velvets. Thehigh or hard twisting of the pile threads serves to increase theirdiameter so that they are substantially coarser than the ground threads,as clearly shown in the drawing, and this gives added strength to the'upstanding pile tufts as well as to the fabric in general. 'I'he factthat the tufts are permitted to remain in 5 their twisted conditioneliminates the -necessity of certain steps in the manufacturingprocedure relating to the finishing of the fabric material, and therebydecreases the cost of production so that this fabric, with all itsadvantages, is very 50 economical to manufacture.

It will be understood that various changes may be resorted to in theform, construction and arrangement of the several parts and in thematerials employed, without departing from the 55 spirit and scope of myinvention; and hence I do not intend to be limited tothe details hereinshown and described, except as they may be included in the claims, nordo I intend words or specic designation in the claims to excludeequivalents for the elements so designated.

What I claim is:

1. A velvet clothing fabric comprising a cut pile composed of highlytwisted cellulose acetate artificial silk thread, the twist being sohigh as substantially to increase the normal diameter of the thread, andthe material being of such characteras to retain said high twist aftercutting andlunder normal conditions of wear, exposure and moisture,whereby the fabric has great durability and compressive resistance andresiliency.

2. A velvet clothing'fabric comprising a cut pile composed ofhighly-twisted artiilcial silk thread of the acetate variety, the twistbeing so high as substantially to increase'the normal diameter of thethread, said increased diameter being substantially greater than thediameter of the ground threads of the fabric, and the material being ofsuch character as to retain said high twist after cutting and undernormal conditions of wear, exposure and moisture, whereby the fabric hasgreat durability and compressive resistance and resiliency.
